This document discusses, among other things, a method including providing a laminate having a first conductive layer, a second conductive layer and an insulator between the first and second conductive layers. A hollow conductive via is formed through the insulator, the conductive via electrically connects the first and second conductive layers. At least one conductive trace electrically connects the hollow conductive via to at least one of the first and second conductive layers. The method further includes forming a channel in the insulator adjacent to the hollow conductive via and the channel surrounds the via. Wherein the channel extends at least part way between the first and second conductive layers, the at least one conductive trace bridges the channel, and the via is isolated from the insulator by the surrounding channel formed adjacent to the hollow conductive via. The via is isolated to prevent separation between the hollow conductive via and at least one of the first and second conductive layers, where the insulator is in a swollen condition.

摘要:
A printed electronic device and methods for determining the electrical value of the device. A dielectric material is contact printed on a substrate using a preset force. The substrate has a pressure sensitive material that is optically responsive in direct proportion to the amount of force imparted by the contact printing. The force of the contact printing causes the pressure sensitive material to form a pattern that is quantifiable to the amount of force. The pattern is then optically inspected and compared to sets of standards in order to quantify the amount of force that was used in printing. The thickness of the printed dielectric material is then calculated based on the quantified force by comparing to another set of standards. The electrical value of the printed material is calculated based on the calculated thickness of the printed dielectric material, the surface area of the printed dielectric material, and the dielectric constant of the dielectric material.

This document discusses, among other things, a flexible circuit or other laminate comprising a first conductive layer and a second conductive layer disposed over the first conductive layer. An insulator is disposed between the first and second conductive layers. A conductive via extends through the insulator and electrically connects the first and second conductive layers. The laminate includes a channel in the insulator. In one option, the channel extends at least part way around the via. In another option, the channel extends at least part way between the first and second conductive layers. In another example, a method comprises providing a laminate including at least first and second conductive layers and an insulator disposed therebetween. A via is formed through the insulator. A channel is formed in the insulator at least part way around the via. The channel extends between the first and second conductive layers.

摘要:
Unfired first ceramic layers 11 and at least one unfired second ceramic layer 12 having a different color from the unfired first ceramic layers 11 are laminated to prepare an unfired ceramic laminate 13. Notches 14 are then formed on a surface of the unfired ceramic laminate 13 using the second ceramic layer 12 as a reference. The unfired ceramic laminate 13 is fired to provide a fired ceramic laminate 13a, which is then divided along the notches 14 into ceramic composites 13b. In this process, notches having the proper depth can be formed on the unfired ceramic laminate 13.
摘要:
Devices and their subassemblies typically undergo stresses during manufacturing and testing processes and during general use. To provide visual indication of stress or strain levels endured, a preferred embodiment includes frangible material deposited on particular isolated areas of devices and/or their subassemblies. The frangible material, when applied according to one methodical embodiment, provides visible indication of overstrain as cracks in the frangible material deposits, and of non overstrain when cracks are not visible.
摘要:
The density (and hence thickness) of a functional ink layer (41) as comprises a part of an active printed electronic component (71) is determined through interaction (13) of the functional ink with light. This information, in turn, facilitates assessment (14) of the likely corresponding electrical performance of the electronic component. When the functional ink comprises a transparent material, a dye can be added to facilitate the desired interaction and assessment.
